As others have stated, Sony gear CAN be setup to run for a couple years.
Careful gain setting is key, and since they were outrageously overrated, most people didn't. With the rise of CEA compliance, it's much easier to set things properly. I still don't believe the rating completely though...
I had a few of their subs and an amp... and consistently they just die for unexplainable reasons.
Pros: Cost, stylish, brand recognition, CEA rating, decent cosmetics
Cons: overrated, unreliable, inevitable failure, poor wRMS/$
Better alternatives: Profile, Crunch, Autotek
